Charging Curve & Charging Speed Analysis

Understanding Charging Performance

Charging performance isn't just about peak power—it's about sustained power across the entire charging curve. A vehicle that maintains 150kW from 10-80% SOC will charge faster than one that peaks at 250kW but quickly drops to 100kW after 20% SOC. The shape of the curve matters more than the highest peak power.

The key metric is C-rate, which accounts for both charging power and battery capacity. A C-rate of 2.0 means the battery can theoretically charge from 0-100% in 30 minutes, while 1.0 C-rate equals 60 minutes. This makes it easy to compare vehicles regardless of battery size.

Charging Curve Shape

Flat, sustained power across a wide SOC range beats high peaks that quickly taper off. Look for vehicles that maintain high power from 10-80% SOC.

C‑Rate & Timing

C-rate normalizes charging speed across different battery sizes. Higher C-rates mean shorter charging times and more flexible road trip planning.
